The Hitch star was announced as the new CK star in February, but was rumoured to have been swiftly dropped after entering rehab merely weeks later for suspected prescription drug addiction.

It has now been confirmed that Mendes will not only be the face of the new Calvin Klein fragrance, but will also front a global advertising campaign for their lingerie.

When asked if Mendes' stay at the Cirque Lodge had effected her relationship with the company, Tom Murry, president and chief operating officer of Calvin Klein Inc. told WWD, 'No, it has not. We were already in one (fragrance) campaign when it (rehab) occurred and it did not affect our decision-making for the underwear campaign.'

Mendes added in a statement, 'The company has such an incredible creative legacy. I'm honored to be associated with such an iconic, world-class brand like Calvin Klein.'

Calvin Klein has a long history of celebrity spokespeople, including Mark Wahlberg, Hilary Swank and most recently Kate Bosworth. Mendes follows in the foot steps of Kate Moss, who starred in both perfume, underwear and jeans advertisements for Calvin Klein during her time as a spokesperson for the brand.
